Hi,
You will get scaled down values. Only you can decide if they are any good for your application...
The math behind ADC isn't difficult, start there.
To get the maximum out of an ADC, you need to get a solid understanding of Sampling Theorem...
Kind regards

Hi,
Is 10mV-50mV peak-to-peak, peak, average, RMS?
What resolution (how many bits) do you need?
Kind regards

Hi,
You'll have to lower your expectations. If you can get the +REF down to 1.7V, you may get 5-6 bits...
I hope that helps.
Kind regards

You need to amplify that signal to match the dynamic range of the ADC if you don’t want to change Vref.
Refer to this application note/section 3.2.6:
